Show 244 MR. M. JACOBY ON THE [Feb. 2, PEDRILLIA MADAGASCARIENSIS, n. sp. Fulvous, pubescent; the apical six joints of the antennas, the apex of the tibias, and the tarsi, black; thorax finely, elytra strongly punctured. Length 1| line. Head broad, very sparingly and finely punctured, with some few hairs; clypeus narrow, semicircular; antennas widely separated at the base, extending scarcely beyond the base of the elytra, fulvous, the terminal seven joints black'; thorax but slightly broader than long, constricted below the middle, the latter projecting angularly, the disc with a shallow transverse groove near the base, the sides below the groove thickened, wdth some stiff hairs, the surface finely and remotely punctured, each puncture provided with a blackish stiff hair; scutellum subtriangular, punctured and pubescent ; elytra slightly flattened along the suture, broader at the base than the thorax, much more strongly punctured than the latter and sparingly clothed with yellowish hairs ; underside and legs fulvous ; the apex of the posterior femora, (sometimes) that of the tibias and the tarsi, black. Hah. Madagascar, Diego-Suarez (Alluaud). This is the first species of the genus known to m e from this locality. In the collection of M . Alluaud and m y own. HEMYDACNE, n. g. Elongate, parallel ; head broad, not constricted ; antennas widely separated, filiform ; eyes small, slightly emarginate; thorax narrowed at the base, without lateral margin ; elytra wider than the thorax, deeply punctate-striate : first two abdominal segments much longer than the following ones; posterior femora slightly incrassate ; the four posterior tibias with a tooth near the apex; the first tarsal joint as long as the two following ones, claws appendiculate; prosternum proportionately broad, yet twice as long as broad, its base truncate. The insect for which this genus is proposed is difficult to place in any of the earlier groups of Phytopbaga, since it exhibits a number of characters peculiar to several of them ; thus the widely separated antennas and the broad head agree with Megascells, the thorax is somewhat similar to Orsodacna, but the broad prosternum and the posterior tibias widened into a tooth at the apex are not found amongst any of these sections. The insect had perhaps best find its place near Orsodacna at present, but would form a special group if other similarly structured species should be found. HEMYDACNE MACULICOLLIS, n. sp. (Plate XVII. fig. 3.) Below black, above and the legs testaceous ; head with one, the thorax with two black spots, remotely punctured; elytra deeply punctate-striate; the interstices longitudinally costate, flavous, the suture black. Length l|-2 lines. |
